Summary
With a dam height of 58 feet and a storage capacity of 750 acre-feet, the reservoir plays a crucial role in supporting agricultural activities in the region. The low hazard potential and not rated condition assessment indicate that the structure is well-maintained and poses minimal risk to surrounding areas.
Managed by the Oregon Water Resources Department, Harpold Reservoir undergoes regular inspections and meets state regulatory standards for operation and enforcement. The reservoir covers a surface area of 120 acres and has a drainage area of 2.04 square miles. Its strategic location in the San Francisco District ensures efficient water distribution for irrigation, while the presence of outlet gates allows for controlled discharge up to 300 cubic feet per second, contributing to sustainable water resource management in the area.
With its long history of providing water for agricultural activities, Harpold Reservoir stands as a testament to the importance of water infrastructure in supporting local economies and communities. The reservoir's Earth dam type and close monitoring of its operations demonstrate a commitment to efficient water use and environmental stewardship. Climate enthusiasts and water resource advocates can appreciate the reservoir's role in maintaining a reliable water supply for irrigation while minimizing potential risks and hazards to the surrounding area.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
